I bought these quite a while ago. I forgot them and found them lately and thought I should use these before they expire. I drank one dose two hours before my practice. I suffered less from lactic acid than normally and my endurance was better. Next time I did the same - with same results. Then I decided to use my husband as a "guinea pig". We had been training two days in a row and this was the third day without rest day in between. We both were already drained before the training session - muscles sore and aiching. But Power Pak did the trick! My husband felt the same - better endurance, more power and less lactic acid. I think this is really working - I'm ordering more!

I take large doses of vitamin c every day, and have done so for decades.
These packets can be brought to work or school, so a hefty dose of my favorite vitamin is never far away.
Elecrtolyte Stamina also contains modest but important levels of several b vitamins and trace minerals. Tasty and refreshing, too. Just pour the packet into several ounces of water, wait a moment while it fizzes, and drink it down.
I believe that nutritional supplements saved my life. I've tried a lot of products, and I know what works and what doesn't. My reviews are honest, straighforward, and based on my experience. Read my other reviews to quickly learn from my three decades of research and experimentation.
